I tried to install some other single bikes too, which they tell me to overwrite the bati.yft, bati.ytd, bati_hi.yft files with the ones of the downloaded archive from gta5-mods website, i tried several of these type of mod, using OpenIV but no luck, when I start the game it donwloads some files again like it was a patch. and when the game itself opens, i found a bati (the non advertizing one, but the one solid color one), but it wasn't the modded bike i choosed, only the "vanilla" bati.
